Abstract

Galaxies, along with their underlying dark matter halos, constitute the building blocks of structure in the Universe. Of all fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds at early times to the galaxies we see today. The interactions among myriads of stars, or dark matter particles, in a gravitating structure produce a system with fascinating connotations to thermodynamics, with some analogies and some fundamental differences.

Ignacio Ferreras presents a concise introduction to extragalactic astrophysics, with emphasis on stellar dynamics, and the growth of density fluctuations in an expanding Universe. Additional chapters are devoted to smaller systems (stellar clusters) and larger ones (galaxy clusters). Fundamentals of Galaxy Dynamics, Formation and Evolution is written for advanced undergraduates and beginning postgraduate students, providing a useful tool to get up to speed in a starting research career. Some of the derivations for the most important results are presented in detail to enable students appreciate the beauty of maths as a tool to understand the workings of galaxies. Each chapter includes a set of problems to help the student advance with the material.

Abstract

This book covers aspects and achievements of the baryonic (star and gas) component of galaxy halos as presented at the successful conference “On the Origin (and Evolution) of Baryonic Galaxy Halos”, held on the Galapagos Islands, Ecuador, March 13–17, 2017. It can be regarded as a compendium of the prominent results in this field. The main focus is the latest simulations and observations of galaxy halos. This compendium is recommended to researchers, and advanced students, as it contains peer-reviewed high quality papers that will meet their scientific needs and help to initiate new research directions. Everything described in this book is the result of a truly collective effort from the participants of the Galapagos conference.
